Packaging classification

According to the packaging methods and material types of the costumes, they can be classified as:

a. Bottles (including plastic bottles, glass bottles, etc.); b. Cover [including outer cover, inner cover, (plug, pad, film), etc.] c. Bags (including paper bags, plastic bags, and composite bags); d. Hoses (including plastic hoses, composite hoses, metal hoses, etc.) e. Boxes (including plastic paper boxes, plastic boxes, metal boxes, etc.); f. Spray cans (including pressure-resistant aluminum cans, iron cans, etc.); g. Lipstick tubes (including lipstick tubes, foundation tubes, mascara tubes, etc.); h. Dress-up pen i. Nozzle (including pneumatic type and pump type); j. Outer box (including flower box, plastic seal, middle box, shipping packaging, etc.). The basic requirements for packaging materials

I. Containers and container Accessories

1. Bottle

The bottle body should be stable, with a smooth surface. The thickness of the bottle wall should be uniform, without obvious scars or deformations. There should be no cold bursts or cracks. The bottle mouth should be regular and smooth, without burrs (rough edges), and the thread and jaw joint structure should be intact and regular. The fit between the bottle and the cap should be tight, without any slippage, loosening or leakage. The inside and outside of the bottle should be clean.

2. Hose

The hose body should be lubricated, regular, of uniform thickness, without obvious scratches, and the color should be uniform and consistent. The hose seal should be strong and regular, without any openings or wrinkles (normal mold indentations are outside). The composite film of the hose should have no floating phenomenon.

3. Lid

The lid is made of PP material, ABS material, sarin material, PTCG material, K material, aluminum foil, etc. Different materials are judged by experience such as contact feel, appearance, and the sound of rebound when dropped. The disinfection methods are also different.

Inner cover: The inner cover should be intact, lubricated, clean and not deformed. The collaboration between the inner cap and the bottle as well as the outer cap should be outstanding. The inner cover should not be left unused.

Outer cover: The outer cover should be regular, lubricated, free of breakage, cracks and burrs (rough edges). The color of the outer cover should be uniform. The threaded cooperative structure of the outer cover should be intact.

The color of the electroplated aluminum or gold-embossed outer cover should be uniform. The outer cover of the flip type should be able to flip up smoothly, and there should be no cracking at the connection parts. The fit between the cap and the bottle should be tight, without any slippage or loosening.

4. Spray can

The tank body should be flat, free of rust spots, with smooth welds, no obvious scratches or concave tank phenomena, and the color should be uniform. The roll of the spray can should be smooth and free of wrinkles, cracks and deformations. The cover of the spray can shall comply with the requirements of 5.3.2.

5. Nozzle

The nozzles should be regular, clean, and free from damage and cracks. The components of the nozzle should be intact and undamaged to ensure the smooth flow of the sprayed liquid.

Ii. Basic Quality Requirements for Flexible Packaging.

1. Bag

The bag should not have obvious wrinkles, scratches or air bubbles. The color of the bags should be uniform. The seal of the bag should be intact, without any openings, perforations or leakage of liquid (paste). The composite bags should be strongly laminated and evenly coated.

2. Plastic sealing

The plastic sealing should be firmly bonded without any cracking. The surface of the plastic seal should be clean and free from damage. There is no misinstallation, omission or inversion inside the plastic seal.

Iii. Basic Requirements for Cosmetic Packaging Materials

1. Ingot tube

The body of the ingot tube should be regular, smooth, free of cracks, burrs (rough edges), and should not have obvious scratches. The color should be uniform and consistent. The components of the ingot tube should be appropriately loose or tight to ensure that the contents can be normally screwed out or pushed out.

2. Makeup pens

The pen barrel and pen cap of the dressing pen should be lubricated, regular, without delamination and the paint film should not crack. The coordination between the pen barrel and the pen cap of the costume pen should be appropriately tight or loose. The color of the dressing pen should be uniform.

Iv. Basic Quality Requirements for Outer Packaging

Industrial hose

1. Box

The surface of the box should be smooth and regular, without obvious exposed scratches, burrs (rough edges), severe dents or damages. The tightness of opening the box should be appropriate. When taking out the flower box, do not forcibly peel it open with your fingers. It is qualified when you pinch the edge of the cover and the bottom does not fall off by itself. The mirror surface inside the box, the contents and the box should be firmly attached, with excellent mirror image, no exposed scratches or damage.

2. Printing and labeling

The pictures and handwriting on the packaging and printing of costumes should be neat, clear, not easy to fall off, and have uniform color. The labels on the packaging of cosmetics should not be wrongly pasted, missed or pasted upside down. They should be pasted vigorously. The label requirements shall comply with the provisions of GB 5296.3.

3. Flower box

The flower box should fit tightly with the middle box packaging. The flower box should be clean, regular and flat, with the lid properly closed. There should be no wrinkles, missing edges or corners. The bonding parts of the flower box should be firmly adhered without any adhesion marks, cracks or mutual sticking. There is no problem of incorrect, missed or inverted installation of the product.

4. Middle box

The middle box should be tightly matched with the flower box packaging. The middle box should be clean, regular and flat, and the box lid should be properly closed. The bonding parts of the middle box should be firmly adhered without any adhesion marks, cracks or mutual sticking. There is no problem of incorrect, missed or inverted installation of the product. The labels on the middle box should be regular, clean and intact. According to the requirements, they should indicate the product name, standard, quantity packed in the box and the name of the manufacturer.

V. Requirements for trademarks, instructions, box head labels and certificates of conformity in the packaging

1) Printed trademarks should have regular drawings, clear color registration, and clear and vigorous handwriting.

2) The trademark should be affixed vigorously and firmly. It must not be tilted, missed, pasted upside down or wrongly pasted. After being affixed firmly, the corners and edges should not be lifted. 3) The printed pictures in the instruction manual are neat and the handwriting is clear. 4) The printed handwriting and pictures on the box head (sticker) are clear. 5) The printed handwriting and pictures on the certificate of conformity are clear, and there are symbols such as the factory name and the inspector's code. 6) The standard number implemented should be indicated on the product or its instruction manual and packaging. 7) Indication of the production date and shelf life or the production batch number and the expiration date. 8) The transportation packaging should be neat, regular and smooth, and the boxes should be tightly sealed. There is no problem of incorrect, missed or inverted installation of the product.

Problems that may occur during the inspection of packaging materials

To sum up, there are mainly two aspects:

I. Process Issues

The color printing accuracy of the inner bag of the mask is not good and the color is incorrect

2. The layout of the inner bag is different from the planning draft (the rounded corners at the edges have become right angles)

3. The paint on the glass bottle peels off and the gilding is misaligned

4. Scratches occurred during the transportation of glass bottles; The gilding on the frosted glass bottle clashes with the bottle body, causing scratches on the gilding

5. The bottle cap is loose, the pump head is tightened, and the gap between the pump head and the bottle shoulder is too large

6. Printing errors (such as incorrect trademark printing, incorrect title printing, incorrect weight printing, etc.)

7. The surface of the set box is uneven

8. The box is deformed, does not stick firmly, and there are glue marks on the box surface

9. Color box printing, gilding at the hot stamping area

10. Hose diameter error (required: 3mm, product: 5mm)

11. The color difference of the packaging materials is too large (comparison of each batch of packaging)

12. The color of the electric eyes on the packaging was changed at will by the manufacturer (the colored dot right in the middle of the end of the toothpaste tube

13. The printed icon on the hose is deformed

14. The glue on the handbag is stuck together

15. The supporting packaging is incomplete

16. The exterior of the packaging is dirty, with dust, glue, handprints, etc

Ii. Material issues

1. The support force of the internal card is insufficient

2. The brightness of the glass bottle is not good

3. The number of composite layers of the hose is insufficient

4. The thickness of the inner bag of the mask is not good

5. The buckle of the inner cap of the bottle is too soft and deforms during the tightening process

6. Some plastic bottles are not heat-resistant, deforming or becoming brittle

7. Plastic bottles become brittle when exposed to light

The above only lists some common problems. There are many other various issues that need to be controlled based on the customer's requirements for packaging materials. For example, there should be no pockmarks on the front of the bottle. Some customers can tolerate this, but it needs to be checked by the inspectors.
